wordpress-bedrock-helm-chart

This chart is for use with wordpress bedrock. In order to use it you must build a custom php-fpm image with the application code located in /var/www/html.

The init container of this chart prepares a volume for /var/www/html, which is then shared between the nginx and the php-fpm container.

The setup is tested on AWS EKS and scales well. A typical setup would look like this:

Cloudfront (blog.example.com) <-> AWS WF       Cloudfront (static.example.com)
       |                                            |
     AWS ALB                                     S3 bucket (filled by wp offload plugin)
       |
     AWS EKS Cluster
       |
     wordpress pods
     |          |
   nginx      php-fpm
         |
   shared volume (EmptyDir synced from /var/www/html)
   
   
         |
      AWS RDS / aurora serverless
